How Do You Reheat Rice?

As we waited for our leftover white rice to reheat in the microwave yesterday, we started to ponder the question of reheated rice. We almost always use the microwave to warm up leftovers, but it often leaves the rice grainy and dry. Is there a better way?

Sometimes we repurpose leftover rice into other dishes, like quick breakfast rice pudding, or fried rice. But when we just want the plain white rice hot again, to serve with other dishes, what's the best way to heat it up?
